On some Kenwoods with the early version WARC bands,those bands come from the factory disabled. Not sure if that was done on the `130 or `120. If it was,there`s probably a diode that needs to be cut to enable 17m operation. Or a wire to be cut to enable the 3 WARC bands,like on the TS-830S. If so,the info should be in your manual.
Did they have a mod for each WARC band? I never knew they came disabled. Good info.
